TH7301EDF

Description
The device incorporates two matching 4th-order Butterworth filters with voltage gain control to perform low-pass filtering on quadrature demodulated signals.
The cutoff frequency and inband gain are programmable via a standard 3-wire interface.
The cutoff frequency can be set between 0.8 MHz and 22.4 MHz and the inband voltage gain can be set between -3 dB and 20 dB.
Features ❐ Wide cutoff frequency range (0.8 MHz to 22.4 MHz)❐ Dual-channel architecture produces superior matching and ease of use for quadrature signals❐ Companding design provides higher resolution at lower cutoff frequencies❐ Low power consumption (<105 mA, typical 55 mA from -5 V supply; Fc = 1 MHz @ 25°C)❐ Single ended or differential input operation possible (AC coupled)❐ No external components for trimming necessary❐ Small package (16-pin SOP)Applications ❐ Digital Broadcasting Systems (DBS) and Digital Video Broadcasting (DVB)❐ Satellite and cable TV decoders❐ Microwave point to point links
